Analysis of the fatigue life of metal composites with a layer of zirconium alloy

Methods of joining dissimilar materials gain interest and attention highly demanding branches modern engineering. Acquiring high-quality bond between steel titanium or zirconium alloys is perceived as especially advantageous in terms high strength corrosion resistance. In the present paper results fatigue tests performed on five different metal composites produced process explosive welding has been gathered. All tested were manufactured by a collision flyer plates with base made steel-titanium bimetal. Fatigue have conducted under uniaxial force-controlled tension-compression conditions constant amplitude load applied parallelly to bonding interface. The analysis includes residual stresses measured hole-drilling strain gauge method calculated three models. A description initiation propagation cracks developing within joint during cyclically changing loading also included. Based collected data, application conclusions formulated regarding optimal use materials.
